Product details

50 MBd digital isolation for high-speed links

The TLP2367(TPR,E is a single-channel digital optocoupler from Toshiba rated at 50 MBd data rate with a push-pull, totem-pole output that eliminates the need for a pull-up resistor on the output side. The 3750 Vrms isolation rating provides galvanic separation for safety-rated interfaces in motor drives, PLCs, and isolated communication ports.

Propagation delay and transient immunity for timing margin

Maximum propagation delay is 20 ns for both tpLH and tpHL, which keeps skew low enough for 50 MBd NRZ data without bit errors. Common-mode transient immunity is a minimum 25 kV/µs — this matters when the optocoupler sits between a noisy power stage and a sensitive controller, because a fast dV/dt on the isolation barrier can couple through parasitic capacitance and corrupt the output. The 25 kV/µs floor means the output stays clean through the switching edges of a 600 V SiC or IGBT bridge.

Frequently asked questions

What is the difference between TLP2367 and TLP2767?

The TLP2767(TP,E is a functional peer with the same 50 MBd data rate, push-pull output, and 25 kV/µs CMTI, but its isolation voltage is 5000 Vrms versus 3750 Vrms on the TLP2367. The TLP2767 comes in a 5-pin SOIC-6 package as well. If your design requires reinforced isolation at 5000 Vrms, the TLP2767 is the drop-in candidate; for basic isolation at 3750 Vrms the TLP2367 fits.

Can TLP2367(TPR,E replace 6N137?

The TLP2367 is a 50 MBd part with push-pull output, while the 6N137 is a 10 MBd open-collector optocoupler. The TLP2367 offers higher speed and eliminates the external pull-up resistor, but the 6N137's open-drain output allows wired-OR connections. Pin compatibility depends on the specific 6N137 package variant; check the footprint alignment between the 6N137's 8-pin DIP and the TLP2367's 6-SOIC before substitution.
